NEC Power-Limited Wiring Requirements:
Power-limited and non power-limited circuit wiring must remain separated in the cabinet. All power-limited circuit wiring
must remain at least 0.25" away from any non power-limited circuit wiring. Furthermore, all power-limited circuit wiring
and non power-limited circuit wiring must enter and exit the cabinet through different conduits. One such example of this
is shown below. Your specific application may require different conduit knockouts to be used. Any conduit knockouts may
be used. For power-limited applications use of conduit is optional. All field wiring connections must be made employing
suitable gauge CM or FPL jacketed wire (or equivalent substitute).
Optional UL Listed battery enclosure must be mounted adjacent to the power supply via Class 1 wiring methods.
For Canadian installations use shielded wiring for all connections.
Note: Refer to wire handling drawing below for the proper way to install the CM or FPL jacketed wire (Fig. 4a).
